To all whom it may concern I Be it lmowu that 1', CHARLES d. lhinrz. a citizen of the United lltates, residing at Gowric, in the county of Websteranc State of Iowa, have invented a new and useful Nut-Lock, of whlch the tollowlng is a. specification.

This invention relates to anut locltand more particularly to that-class of nut locks in which the nut; is compressed against the bolt to prevent the turning of thc said out.

An. object of the present invention. is to provide a nut lock which may be easily and readily assembled in position upon a bolt and securely locked thereto.

A further objectis to provide a nut con1- posed at two parts and Suitable means upon their contacting surface for the insurance of the alineinent thereof upon a bolt previous to the insertion thereon or the locking nut.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combinatiou and arrangement of parts and in that chaugcsin the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

in the drawings acoinpanying this specification and forming a part thereof, the preferable form of my invention is illustrated, in which Figure 1. is a cross sectional View illustrating n iy improved nut lock fastened securely to a bolt. Fig. 2 is a similar view been removed. two parts of 1g. is a view showing the the nut separated a distance apart previous to the insertion thereon of the locking out.

' which similar reference numerals designate corresponde several views. 1 represents the bolt cd end 2 upon. which threaded end is illustrated my improved nut lock.

The numeral 3 represents the nut with l an extension'formed integral therewith and projecting therefrom. The' nut and extension ternally thread- 3 and 4c are i. ed as at 5 to thereby threadedly engage the portion 2 of the bolt. provided, with the exterior threads 6 which are preferably cut upon a conical surface as illustrated. The

construction hereinafter do pro ecting lugs and the corresponding t-i'ohs of the nut 3 I threaded The extension 4 is extension 3 and 4.- are parted longitudinally as more clearly illustrated in Fig.3 and when positioned devised to'be spaced a slight distance apart in order that the locking nut hich threadedly changes the exterior threads 6 is adapted to 'orce the two parts of the nut'and extension together and to thereby securely lock them upon the bolt :2. Tie locking nut 7 is provided with the interii'ir threads preferably out at. a slight angle in order to suitably engage the threads 6 or the eatension in order that the two parts '01 the nut and extension may be readily assembled upon a bolt and furthermore in order that thetlu'eadsforined thereon may c more easily placed in proper alineinent, the projecting lugs 8 are formed upon the portion 3, and the adjacent portion thereto is formed with the deprcssioi'is or pockets 9 in which the said lugs'8 are adapted'to ertend. In the present instance there are two of the projecting lugs-8 and two of the corresponding depressions 9 therefor but it is to be understood that the extension 4: may be provided along nut and aper tures or depresions therefor. reason of the pflojecting lugs 8, the longitudinal por and extension 4- may be readily assembled upon a bolt and by the lugs tting in their corresponding dcpres' sions, the proper alineincnt of the threaded nut upon the two portions will be secured.

my improved nut lock what I claim to be new and original with me 18 In a device of the character described, a two part longitudinally divided nut, a two part longitudinally divided externally extension carried thereby, said extension and nut provided with a threaded aperture extending thel'ethrough, a plurality of cylindrical projections carried by the contacting faces of I nut parts. the opposite portion of said nut provided with a pluraliitv of cylindrical bores adapted tov receive said cylindrical projections therein, said cylindrical PI'OJGClZlOIlS interlocking with the said cylindrical bores and holding the two parts of the nut and extensionagainst relative movements, and a locking nut provided with internal threads extending thcrethi'ough adapted to threadedly engage said extension} transverse and longitudinal and to force the parts of the said-nut and In testimony that I claim the foregoing extension togetheg'the two part nut and eX- as my own, I have hereto afikedmy signatension adapted to engage the threaded orture in the presence of two witnesses.
